Research released by Wi-Fi specialist XCellAir claimed that operators could fail to exploit an opportunity to save costs of almost $18 billion (€16 billion) if they continue to poorly manage unregulated spectrum. The study, conducted in partnership with independent telecoms analyst Real Wireless, said poor management of Wi-Fi assets severely limits the usefulness of such assets in dense urban environments where many access points are deployed to serve large numbers of users and large volumes of data. Interference between these access points, and minimal spectrum management, means that the user experience is often sub-optimal, the report added. Report
